Choose red meats low in fat such as top loin, top sirloin, bottom round, round tip roasts and round steaks.

Show transcribed image text An alkane which can exhibit optical activity is: neopentane 3-methylpentane J-methyl thane 2.3-dimethylbutane How many stereoisomers are possible for the following molecule?
An abbreviated list of some of the most important families of optical polymers and co-polymers includes the following: Acrylic is one of the most commonly used optical plastics. Acrylic options are very hard and have very good mechanical stability. Acrylic has an index @588nm of 1.49, and an Abbe number of 55.3. Acrylic is also known for its very good clarity and excellent transmission properties throughout the visible portion of the spectrum. Polystyrene has a higher index @588nm of 1.59 and lower Abbe number (30.87) than acrylic. It is generally less expensive than acrylic. The material also tends to absorb somewhat in the deep blue spectrum.
